Problems solved by technology

[0002] Generally, winches and pulleys are used to move the fully mechanized mining, drag the bracket to the entrance of the lane for loading, and transport the rails or rubber-tyred vehicles to the next working face or go up the well for maintenance. However, due to The lithology of the floor of the roadway for cutting and removing the frame is soft, with many ups and downs and a large slope, which brings great difficulties to the trailer and seriously affects the preparation time for the removal of the frame and the installation of the mining face

Abstract

The invention relates to an underground support dismantling and mounting method, in particular to an underground fully-mechanized mining support dismantling method applied to dismantling and mounting of supports in roadways and cut holes with high unevenness level, high gradient t and soft floor rock. The method has the advantages that effectiveness of dismantling time is guaranteed by decreasing friction between the supports and the roadway floor, shifting efficiency is improved, load of carriers is lowered, equipment loss and maintenance are decreased, and time is gained for extraction.

Description

technical field [0001] The invention relates to a frame removal and installation technology for a fully mechanized mining face in a coal mine. Background technique [0002] Generally, winches and pulleys are used to move the fully mechanized mining to drag the support to the roadway for loading, and the rails or rubber-tyred vehicles to transport it to the next working face or go up the well for maintenance. The large slope brings great difficulties to the trailer and seriously affects the preparation time for removing the trailer and installing the mining face. Contents of the invention [0003] The purpose of the present invention is to lay out the frame removal track group to reduce the friction between the support and the bottom plate and improve the withdrawal time of the trailer for the uneven bottom plate, large undulations and steep slope of the cut hole and the withdrawal roadway. [0004] The installation method of the downhole frame removal of the present inve...
